Résumé : |
Since the early 1800s, traditional solvent-based coatings have been manufactured and used extensively in the United States to protect interior woodwork, including commercial and residential floors. However, to meet the growing health and environmental concerns, regulatory agencies throughout the world have begun to reduce the allowable amount of volatile organic compounds (VOC) that coatings can release into the atmosphere. These regulations have initiated the transition from solvent-based to water-based coatings.
Early water-based coatings technology did not offer the same level of durability as solvent-based systems, so the use of external crosslinkers emerged. Crosslinkers such as aziridines, isocyanates, and carbodiimides have been and continue to be used to increase the durability of water-based coatings. Each crosslinker brings with it positives and negatives, but they all improve coating properties to some degree. Aziridines and carbodiimides react with carboxyl groups present in most water-based acrylics and urethanes, while isocyanates typically require hydroxyl-functionality to maximize their benefits. |
